UNITED STATES PATENT OFFICE.

HENRY M. GOODMAN, OF LOUISVILLE, KENTUCKY, ASSIGNOR OF ONE-SIXTH TO J.S. BELL AND F. A. BAKER, BOTH OF SAME PLACE.

SELF-OILING CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 438,999, dated October21, 1890.

Application filed August 2, 1890. Serial No. 360,813. (No model.)

. To all whom it may concern:

Be it known that I, HENRY M. GOODMAN, a citizen of the United States,and a resident of Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in SelfOiling Car- Trucks; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of the invention and is aside elevation. Fig. 2 is a vertical section of the axle-box. Fig. 3 isa detail view of the brass inverted.

This invention relates to certain improvements in car-axle lubricators;and it consists in the novel construction and combination of parts, ashereinafter disclosed.

In the drawings, A refers to the car-axle box, constituting the oil orlubricant reservoir. B is the brass, and O the wedge.

D is the lubricant supply pipe, having screw-threaded connection withthe top of the axle box or reservoir A and communicating with a passageformed by central registeringapertures a a, provided in the wedge andbrass, respectively. The pipe D passes up through the truck-frame,butisnot connected thereto.

The brass B, in addition to being concave, as at b, on its under side,conforming to the axle, is provided in the concavity I) thus producedwith a longitudinal channel or groove 0, having at its sides a series ofbranches or arms 0' to uniformly or evenly and thoroughly distribute thelubricant or oil upon the axle. This arrangement or provision is madefor each box of the car-truck, and the supplypipes D of the respectiveboxes are connected at a common point, and to the same is con:

nected by a universal or ball-and-socket joint a flexible or hose pipeE, connected to a discharge-pipe F of the oil or lubricant tank G,secured upon or carried by the car. The tank has a filling-openingsuitably closed byaplug or cap (1, also a safety-valve c to regulate theair-pressure in the tank, and an oil-gage f to ascertain the height oramount of oil therein,

and by means of a pipe-connection efiected between an air pump orcondenser or cyl1nder containing compressed air and the tank 5 5 at gthe oil or lubricant is discharged or fed under pressure.

H is a waste-pipe for the lubricant, one provided for each box of thetruck and connecting under and about centrally of the same with awaste-reservoir, thus collecting the waste lubricant or oil. In case thesupplytank should be placed upon the under side of the car-body, it iscontained in a closure or case, whose door is secured under a lock andkey, permitting the ready inspection of the gage to ascertain thequantity of oil or lubricant in each tank; also, condensed air or steamor gas may be used to force or feed the liquid or lubricant to theboxes, or this may be accomplished by gravity.

This invention is equally applicable for use on locomotives andstreet-cars.

Having described this invention, what I claim, and desire to secure byLetters Patent, 7 5 1s- 1. The combination,withthe wedge having theaperture therein, the brass having in its concavity a longitudinalchannel or groove having lateral arms or branches, and the cen- 8o tralaperture therein communicating with said channel and registering withthe opening in the wedge, of the oil-supply pipe communicating with thepassage formed by the aperture in the wedge and brass and thereby withthe journal, and the discharge or waste pipe, substantially asdescribed.

2. In an axle-lubricator, the combination, with the series ofoil-chambers, of the axleboxes of a truck having their respective supoply-pipes uniting at a common point, as also their series ofwaste-lubricant pipes connecting at a common point with thewaster-escrvoir, and the supply-tank having its discharge or feed pipeconnected by a hose or flexible pipe with the supply-pipe of said oilchambers or boxes, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.

H. M. GOODMAN.
